PANIC! Killer jellyfish invading the seas of Japan!

Killer jellyfish population explosion warning08/02/2008 – Telegraph
…The really bad news is that the box jellyfish and another equally poisonous species, Irukandji, are on the move….
…perplexed Japanese salmon fishermen are seen hauling in tonnes of box jellyfish in their nets. The few fish they do haul in are writhing in their death agonies after being stung.
….the Japanese government to protect their fish stocks by wiping out the swarms using a fleet of commandeered fishing boats to drag razor-sharp wire through them backfired spectacularly…because they are genetically programmed to ensure their survival by producing more offspring than normal when under attack…jellyfish are multiplying in the Western extent of the Pacific ocean and threatening 20,000 miles of coastline off Japan...more...

The Telegraph reporters were smoking jellyfish when they wrote the above article. Jellyfish are multiplying wildly because of overfishing but box jellyfish, Habu-Kurage in Japanese, were not the type of jellyfish the government tried “to protect their fish stocks” from—it was 450lb/200kg Nomura’s Jellyfish aka echizen kurage and I reported on them back in 2005 in Attack of the giant jellyfish! (2005) as you see below.

The the real problem jellyfish is not that they are poisonous but they’re just too numerous. As in the below photo I took last summer, just take a peek over the edge of a dock on Tokyo bay. Any place where the waves are somewhat still, amongst the Japanese-love-of-nature litter, the water looks like you could walk across it over the seething mass of jellyfish.

Are giant jellyfish evolving to take over the seas?io9.com | Sept. 15, 2011
With fish numbers all over the world falling thanks to overfishing and habitat destruction, a surprising predator has sprung up to take their place — the jellyfish. Due to their low energy requirements, the floating blobs of stingers don’t need to be quite as active or accurate to spread and fill the ecological niche afforded them by changes in the ecosystem.
Even more curiously, the jellyfish appear to be adapting to be better hunters, too. An active predator fish has to spot prey and chase after it, but the Medusozoa just passively wait for their prey to come into contact with their poison stingers. So jellyfish are evolving into larger and even slower moving organisms, able to cover more area with their tendrils while still needing only small amounts of energy to survive.MOAR!….
